HPE Synergy TCO Calculator: Facilities cost overview and methodology


This document is the one in a series that identifies the rationale, methodology, formulas, and supporting third-party sources used in the HPE Synergy Business Value Calculator available on (TCO Calculator) assessment of the key costs elements within an analysis. If not done so already, please first review the paper HPE Synergy TCO Calculator overview prior to reading this reference guide. This paper discusses the data center energy-related facilities costs including equipment power usage, cooling requirements, and carbon footprint emissions when migrating from existing legacy servers to a new HPE Synergy Composable Infrastructure.


The HPE Synergy Business Value Calculator provides an initial preliminary economic assessment or total cost of ownership (TCO) analysis for a technology consolidation refresh (brownfield analysis) when migrating from legacy HPE and Cisco blade servers to a new HPE Synergy Composable Infrastructure. There are many financial factors to consider when making a decision to replace existing IT systems. As a result, the TCO Calculator provides a very comprehensive analysis inclusive of the cost elements listed in Table 1. The data center facility (power and cooling, co-location, and carbon footprint emission) cost elements being the topic of this paper.
Meeting energy requirements within today's data center while obtaining optimal efficiency is often a significant concern. In some cases, the additive yearly facilities costs including the needs to power and cool IT equipment can approach or even exceed the purchase cost of the equipment itself. Per an IDC data center power and cooling survey, the costs for power and cooling and the costs for the IT equipment are the two largest components of a data center budget, each as at 24%.
